Calls with “No Caller ID” are generally from telemarketers, hackers, or spammers who are attempting to steal personal information from you. They have disabled their caller IDs on their end to hide their phone numbers, so you won’t be able to file a complaint against them. As a result, some users want to keep their caller ID concealed for privacy and security reasons.
If you find these unknown calls bothersome, you can simply block “No Caller ID” calls on your Android or iOS smartphone to get rid of them. You may do this by calling your telecom service provider and requesting that No Caller ID calls be blocked.
